The first is a brilliant tree build at the Museum of Singapore, traditionally associated with a grand old Banyan Tree, but now with a new, glowing metal contemporary take on the Banyan. The Farm site http://www.farm.sg/work/project/the_tree has images of the tree in the gardens, with people interacting in much the same way they might with a real banyan, as well as drawings and specifications showing how the tree was made.

The Breath of Life is another project over at Design Milk (http://design-milk.com/a-breath-of-life-by-fraser-ross/#more-61797) that caught our eye. While this first version isn't quite a tree yet, there are lots of possibilities here.Scotland -based artist Fraser Ross has used shape changing alloy and LEDs to create a plant that reacts to the carbon in the human breath. There's a video on the site showing how the plants light up, move and change. Pretty usual stuff in virtual worlds, but not so easy to do in real life.
